Welcome to the site & greetings from S.E. Mi.
my 1st 1911 was a (Then) new 80 series Gold Cup.. bought from a a m/c riding friend.
He had a 70 series GC & bought the 80 series , to see if he liked it better.
Shot 1 box of shells with the 80 series, decided he didn't like it, & sold it to me.
I still have it.
